Answers:

1. False. While your body rests, your brain does not work. An active brain during sleep prepares us for alertness and continue functioning the next day.
2. True. Most adults need around eight hours of sleeping to function at their fullest capacity. To determine your sleeping need, sleep until you wake up on your own…without an alarm clock. Feel alert? That’s your sleeping need. You can teach yourself to sleep less, but not to need less sleeping.
3. False. Sleep loss causes sleepiness. Boredom, like a warm or dark room, merely unmasks it.
4. True. Rest is not a substitute to sleeping. Sleeping is as necessary to health as food and water. When you do not get the sleep you need, your body builds up a sleep debt. Sooner or later, this debt must be paid… with sleeping.
5. False. Snoring may indicate the presence of a life-threatening sleeping disorder called sleeping apnea. People with sleeping apnea snore loudly and wake up repeatedly during the night, gasping for breath. These repeated awakenings lead to severe daytime sleepiness. Many people with sleeping apnea are unaware they have this condition.
6. True. Though many people fail to remember their dreams, dreaming does occur for every person, every night. Dreams are most vivid during REM or rapid eye movement sleep.
7. False. Sleeping need remains unchanged throughout adulthood. Older people who sleep less at night tend to sleep more during the day. If poor sleeping habits, pain or health conditions make sleeping difficult, a physician can help.
8. False. If you are sleepy enough, you can fall asleep anywhere. it is also possible to fall asleep for a few seconds and not even realize it. These “microsleeps” can be dangerous if they happen when you are driving.
9. False. Playing a radio, chewing a gum, and opening windows are not great ways to keep sleepy drivers alert because their effects are short-timed. If you are having trouble staying awake while driving, try to pull over at a safe place and take a short nap or have a caffeinated drink. The best solution is to drive after a good night sleep.
10. False. Sleep disorders occur due to a variety of causes. Sleeping apnea, for example, is caused by obstruction of the airway during sleep. Narcolepsy is characterized by severe daytime sleepiness and sudden sleep attacks, and it appears to be genetic. No one knows yet what causes restless legs syndrome, in which creepy, crawly feelings arise in the legs and are relieved, momentarily, by motion.
11. True.  All living things (people, animals, even plants) have a circadian or about a 24-hour rhythm. This affects when we feel sleepy and alert. Whether you work a night shift or not, you are most likely to feel sleepy between midnight and 06:00 am. Therefore, a shift worker’s circadian rhythm never adjusts.
12. False. Sleep disorders do not disappear without treatment. Treatment can be based on behavioral modes (for example, going to sleep and waking at the same time every day), pharmacological, surgical or a combination. Untreated sleep disorders may have serious consequences in your health, quality of life, school or work performance, and relationships. In the worst-case scenarios, untreated sleep disorders can lead to accidents and death.
